我有实现模型：

# encoding : utf-8
class Realization < ActiveRecord::Base
  attr_accessible :city, :street, :title, :work, :photo, :date

  has_attached_file :photo
end

控制器：

# encoding : utf-8
class RealizationsController < ApplicationController
  before_filter :admin_required, :except => [:index,:show]

  # GET /realization/new
  def new
    @realization = Realization.new
    @realization.date = Time.now.__send__(:to_date).to_s
  end

  # POST /realization
  def create
    @realization = Realization.new(params[:realization])

    if @realization.save
      redirect_to @realization, notice: 'realization was successfully created.'
    else
      render action: "new"
    end
  end

(...) others

表格视图：

<%= form_for @realization, :html => { :multipart => true } do |f| %>
    <% if @realization.errors.any? %>
        <div id="error_explanation">
          <h2><%= pluralize(@realization.errors.count, "error") %> prohibited this realization from being saved:</h2>

          <ul>
            <% @realization.errors.full_messages.each do |msg| %>
                <li><%= msg %></li>
            <% end %>
          </ul>
        </div>
    <% end %>

    <div class="field">
      <%= f.label :title %><br />
      <%= f.text_field :title %>
    </div>
    (...)
        <div class="field">
            <%= f.file_field :photo %>
        </div>

    <div class="actions">
      <%= f.submit "Submit" %>
    </div>
<% end %>

和路线：

resources :realizations

而WEBrick服务器信息是：

Started POST "/realizacje" for 127.0.0.1 at 2013-04-12 12:26:35 +0200

  Rendered realizations/index.html.erb within layouts/application (156.0ms)
Completed 200 OK in 340ms (Views: 333.0ms | ActiveRecord: 4.0ms)

当我使用表单并推送提交时，它重定向/randers 实现/索引，甚至没有通知或错误！我完全不知道为什么？特别是它以前工作过......也许后来添加的javascript可能是原因？回形针在更新中运行良好，所以不是......

您可以检查您的新操作以查看您传递给 form_for 的内容。

您希望传入您的实现模型的全新实例。

即在新操作中，您应该有一行显示@realization = Realization.new

我建议这样做的原因是因为 form_for 在您提供给它的对象上调用了一个方法（#new_record？），并将根据该方法调用返回 true 还是 false 来提交 post 或 put 请求。
